PARALLEL VISE.

Application filed August 29; .1ML Serial No. 496,524.

To allzu/Omit vit/ffy conce/n Be it known thiit I, ALFRED Oene, it citim zen of the Gernuin Republic, and e resident oli' Hamburg, Germany, have invented cerf tein new and useful improvements in Perellel Vises (for which l have iiled n appliestion in Germany on Aug. 16, 199.1), ot which the m,tollowing .is specification. A

lili' iifii'ention relates to s j jei'zillel viseg more especially to a parallel vise ot novel constriuzticiu wherein the jews may be turned, inclined and positioned withxthe spindle on end, i. e.,\f'ertic2tl.`

The object ot my invention is' `to'provide a parallel vise meeting all requirements in regard to adjustsbility, :i vise that will readily taire ell working pieces, even such ot odd shapes end of; bulky forni und that will hold them rigidly in any position reqilired by the work to be performed on 'them and by the conditions ot light pre iai it the piece oit work, i

further advantage of in); novel wie resides in that all parte suljiiected to weer muy be readily le: djnsteifl, und that the jews ure equally well lf iuided end supported Lt ll widths ot grip. The front jaw meg; z, ,ie inclined side-wziys by itself.. 'facilitatc l P; tie change ot jew-plates in both jaws, since with the tront jew inclined the screws ere more readily accessible. rl`lie arrangieuient olz the` eye-bolt between the two jaws @nues the pressure to be well received end lrmfsniittcd to the workiui tab-le.

The vise will else take lei'gre size plates in horizontal position us it may be put onend i. e. with the spindle vertical. and the vise, muy also be turned when in the onend ilicsition. i

The front jiilw 72; being' slotted below v. its boring., is clamped tight onthe bush l by Ineens fot the screw g. The back z, is also slotted below1 es is also the bush (Z. The slot in bush c?y however.4 extends onlji7 along' the portion oli' the bush projecting` from the eyel; i` Zi. nut 7c (cont. Figs. 6 and 7) is iffiisitioned on the screw-snindle i sind is si, scented to vhe screwed Yforward and; baci*- furd freely. The nut 7c is provided with :i el. which is e'i'iided within the slot of the juide bush (Z is clamped in the slot ot the il bflcl jew la, by ineens of the screw Z. It th., screw spindle i is beine' turned the beck degrees. Fifi'. 9 shows the vise turned hv Qt eind 'nolinedto the lett by about 600.

The outside diameter ot the bush d and the inside diameter ot the borine' in the bracket a are exactly the same sind consequentlj'. it the tree end ot the bush d is placed into the bracket a, the whole vise may be put on-end as is shown, in Fig. l0. The slot in the baci jaw permits the jew to be clamped tight on the guide-bush. allowing also 'tor weer. The width ot grin et the vise may be increased et :i slight edditionzil cost by merel;7 desinine' the guide bnsh d and the screw-spindle z' of @greater length, the jswsbeing equally well guided end supported at all width of grip.

After having thus particularly described the nature of my invention. what I claim es new and desire to secure by Letters Patent of the United States is:

1. et parallel vise oft the adjustable time. comprising in combination e. bored bracket partly slotted. an eye-bolt disposed in seid bracket, a guide bushingfof round sectional shape, said bushing being partly slotted and adapted to be journaled and fixed Within the eye oi' said eye-bolt, a slotted front jaw, clamped onto the non-slotted section of said guide-bushing, a bolt adapted to effectlthe' clamping of said front jaw, a slotted backjaw positioned on the--s`lotted part of said guide-bushing, and a screw vfree to rotate Within said bushing. t

2. A parallel vise of the adjustable tyne comprising in combination a bored bracket partly slotted, an eye bolt ,disposedv in 'said bracket, a round guide-bushing lpartly slotted and adaptedV to be fixed Within the eye of said eye-bolt, al frontjaw and a back jan-7 positioned on the non-slotted and slotted sections of the said busb respectively `a spindle free to rotate lwithin thesaid busliing, a. tailedr nut positioned onv the` said spindle and adapted to be screwed backward and forward Within the said bushing, the tail of said ,nut being vextended into the slot of said bushing, a bolt adapted to clamp said tail of the said nut to said back jaw, the latter being adapted by means oit this connection to be moved backward and forward on the said bushing.
